We're learning a lot about our tiny corner of the cosmos these days. That's thanks to improving technology and the increasing number of probes we're sending into the solar system.
But as much as we learned so far, there’s still a lot about space that we don't know.
Recently, researchers have been trying to track down a theoretical Planet Nine. (That's the title formerly held by Pluto. Sorry, Pluto.)
University of Michigan astronomers recently came across a planetary surprise that might get us closer to that discovery. And it turns out Pluto might have a friend out there after all.
